You're Making Calls and Questioning Your Life — Here's Why
A company selling castings and hydraulic components ran an internal post-mortem: its regional sales team had dialed 320 outbound calls in a single month, but only 19 of those reached a factory purchasing decision-maker — a conversion rate below 6%. The rest of the calls either landed on system integrators with no in-house production lines, or on small assembly shops that outsource everything and have no direct demand for castings or hydraulic parts at all.
At a loaded salary cost of ¥25,000 per sales-person-month, those 320 wasted calls consumed more than 80% of the month's total dialing hours, equivalent to roughly ¥20,000 in squandered labor. The larger loss was opportunity cost: that time could have gone to genuine equipment manufacturers showing capacity-expansion signals, actively sourcing hydraulic systems and castings.
The problem is not the pitch. It is not the product. It is the quality of the list. The machinery and equipment sector spans a broad range of sub-industries and long supply chains. Without a systematic method for identifying real customers, upstream suppliers will keep bouncing randomly between integrators, traders, and genuine factories.
What Machinery and Equipment Factories Actually Look Like
Wide Size Range — the 8,524 Scale-Up Enterprises Are Just the Tip of the Iceberg
In 2024, the general machinery industry counted 8,524 enterprises above the designated scale (China General Machinery Industry Association operating data, 2024). Value-added output in the equipment manufacturing sector grew 7.7% year-on-year, accounting for 34.6% of total industrial value-added above the designated scale. Annual revenue for the machinery industry as a whole crossed the ¥30 trillion mark for the first time, reaching ¥31.5 trillion (National Bureau of Statistics, 2024 Statistical Communiqué on National Economic and Social Development).
The "above designated scale" threshold is just a statistical boundary. The factories that actually drive castings and hydraulic-component purchasing span a wide range — from ¥10 million to several billion yuan in annual revenue. High-end equipment is concentrated in the Bohai Rim and the Yangtze River Delta: heavy-equipment bases in Shenyang and Dalian; general-machinery precision machining clusters in Suzhou and Ningbo; and fast-growing new equipment production zones in central and western China. Drilling down to pumps and valves, Wenzhou in Zhejiang is one of the most concentrated valve production areas in the country; gas-separation equipment is dominated by a handful of specialized enterprises; and compressor production zones run from Shanghai through to Shenyang.
This pattern of cluster concentration carries a direct implication for upstream sales: going deep inside one industrial cluster is several times more efficient than scattering calls nationwide.
Real Factory vs. Integrator / Trader — Three Hard Differentiators
The machinery and equipment sector is where the line between integrators and real factories is hardest to draw. The industry is full of "solution integrators" — companies that source externally assembled sub-components and deliver complete systems under the banner of "equipment manufacturing." They look like manufacturers on paper, but they have no in-house casting machining capability and no proprietary hydraulic-component production line. They are not a direct purchasing party for castings or hydraulic parts.
Differentiator 1: Is there a machining workshop? A genuine equipment manufacturer has at least basic turning, milling, grinding, and drilling capability, backed by real equipment assets. An integrator's facility may consist of nothing more than an assembly bay and a warehouse — no machining equipment at all.
Differentiator 2: Is there in-house casting, welding, or heat-treatment capacity? Core structural components in heavy equipment typically require castings or welded fabrications. A real factory either has its own casting line or has long-term, stable casting purchase contracts with documented inbound records. Integrators cannot even manage the process drawings for castings, let alone maintain a deep supplier relationship.
Differentiator 3: For pressure-vessel or special-equipment product lines, does the company hold a TS manufacturing license? Pressure vessels, pressure piping, and similar special equipment require a nationally mandated TS manufacturing permit. Real factories carry this certification on file; integrators typically do not obtain it, because they do not actually produce this class of equipment. For export products, look additionally for CE certification or equivalent market-access marks; ISO 9001 quality-system certification is the baseline threshold in this industry.
Three Steps to Finding Machinery Factory Customers
Step 1 — Lock Down Your Target Factory Type by Casting or Hydraulic-Component Application Segment
Castings and hydraulic components serve widely different downstream equipment types. The first thing a sales team must clarify is which equipment category its product serves and at which stage in that equipment's production:
- General pump and valve equipment: makes heavy use of cast-iron and cast-steel valve bodies and balls; hydraulic-component volumes are moderate, but purchase frequency is high; clusters in the Wenzhou valve industrial zone in Zhejiang and the Hefei pump industrial zone in Anhui
- Construction and mining machinery: the hydraulic system is the core; hydraulic pumps, motors, and multi-way valves are purchased in large volumes; supply-chain factories around Changsha (Sany, Zoomlion) and Xuzhou (XCMG) are priority customers
- Heavy pressure vessels / chemical equipment: castings used in flanges, heads, and nozzles; hydraulic components used in pressure test benches; concentrated in Suzhou and Nantong in Jiangsu, Ningbo in Zhejiang, and Lanzhou and Shenyang
- CNC machine tools / machining centers: beds and columns are typically large gray-iron castings; hydraulic clamping systems are a standard requirement; machine-tool factory clusters in Beijing, Shenyang, Dalian, and Ningbo
Whichever application segment your product serves, that segment's industrial cluster is the natural first circle to search — not a nationwide broadcast.
Step 2 — Use Four Industry Signals to Identify Factories That Are Actively Buying
Machinery factory purchasing windows have clearly event-triggered characteristics. The four signals below represent the most valuable entry points:
Capacity expansion / major equipment investment. When a machinery factory announces additional machining centers or machine tools, a new plant under construction, or a capacity increase, casting and hydraulic-component purchases tend to spike at once. In 2024, general machinery exports reached ¥17.227 billion, up 14.34% year-on-year (China General Machinery Industry Association), and that export growth reflects a cohort of factories in rapid expansion mode. These signals typically appear in factory website announcements, local industrial-park news, and government investment-attraction bulletins — but manual monitoring is extremely inefficient.
New application for, or renewal of, a special-equipment manufacturing license. A TS permit application or annual renewal is one of the strongest purchasing signals available — it means the factory is expanding its product scope or upgrading production capability, which translates directly to new process equipment and component procurement. This signal is routinely missed by upstream suppliers, yet it is one of the best entry-point opportunities available.
Hiring machining or assembly engineers. Factory job postings for "CNC operators," "hydraulic system commissioning engineers," or "casting process engineers" signal that production lines are expanding or new product lines are being brought in — a leading indicator of bulk consumable and component procurement. This publicly available information updates in real time, but aggregating it across platforms demands enormous manual effort.
Winning a contract as a supply-chain partner on a project tender. Machinery factories that win large-project contracts — for power equipment, chemical systems, environmental equipment, and so on — move into a procurement and materials-staging phase immediately after award. Public tender and award notices are the most direct evidence that a factory has just landed a large order and will be purchasing heavily over the next three to six months.
Manually chasing down all four signals for every prospect is impractical. The efficiency gain comes from integrating signal filtering and factory-authenticity verification into a single workflow.
Step 3 — Use Tianxia Gongchang to Lock Down Real Equipment Manufacturers, Then Export the Follow-Up List
Steps 1 and 2 narrow the search direction. Step 3 requires a tool that can distinguish real factories from integrators and traders, completing the final verification before resources are committed.
Open Tianxia Gongchang, select the "general machinery" or "equipment manufacturing" industry category and the relevant sub-segment, layer in the industrial cluster region (Wenzhou / Suzhou / Changsha / Ningbo), set the enterprise size range, and generate the candidate list.
The key action: Tianxia Gongchang covers 4.8 million real manufacturing enterprises in China and has run factory identification on every entity. Each record in the list is labeled with whether it is a genuine manufacturing entity, allowing you to directly filter out integrators and equipment traders with no in-house production capacity. Log in to Tianxia Gongchang, run one filter pass by industry and industrial cluster, then compare the record count before and after the factory-attribute filter is applied. That difference is exactly the volume of calls that would otherwise have been wasted on dead-end visits.
Once the list is exported, apply the four signals from Step 2 to set priority order: factories with a capacity-expansion announcement and recent engineer job postings go to the front of the visit queue; factories with a TS license status change enter the urgent follow-up sequence; the remainder go into a periodic nurture cycle.
How to Use Tianxia Gongchang in the Machinery and Equipment Sector
The Factory-Identification Baseline: Filtering 4.8 Million Enterprises for Real Manufacturers
Tianxia Gongchang's core capability is separating genuine manufacturing entities from non-factory entities. In the machinery and equipment sector, this capability is especially critical. The "manufacturer" label in this industry has been diluted by a large number of system integrators, equipment traders, and registered shells with no production line. An ordinary business-registry database cannot determine from registration records alone whether a company actually has a machining line and casting capability.
Tianxia Gongchang front-loads the real-factory identification step. The 4.8 million real manufacturing enterprises in its coverage have already had factory-attribute verification applied before you run your first search. Sales teams selling castings and hydraulic components do not need to spend a week manually verifying who is a real factory and who is an integrator before starting to prospect — Tianxia Gongchang has already done that work.
Business-registry lookup tools such as Qichacha can surface registration records, but they cannot tell you whether "this company actually purchases castings and hydraulic components." The "equipment manufacturers" listed on 1688 and in industry directories are similarly mixed with large numbers of trading entities that have no in-house production capacity. Tianxia Gongchang has built an independent judgment mechanism at the factory-identification layer, so that upstream sales start list-building on solid ground from day one.
The Machinery and Equipment Screening Workflow in Tianxia Gongchang
When running a machinery and equipment search in Tianxia Gongchang, we recommend stacking the following filters in order:
- Industry category: general machinery / equipment manufacturing (optionally drill down to pumps and valves, compressors, construction-machinery components, pressure vessels, etc.)
- Industrial cluster / region: Yangtze River Delta (Suzhou, Ningbo, Wenzhou), Bohai Rim (Shenyang, Dalian), greater Changsha — select based on your sales coverage territory
- Size range: mid-tier factories as the primary target, supplementing with small factories that have demonstrable capacity-expansion capability
- Factory-attribute filter: display only records identified as genuine manufacturing entities, filtering out integrators and traders
- Export the list, then apply a secondary priority sort using TS license status, recent hiring activity, and recent tender-award information
Tianxia Gongchang integrates all of these filter layers into a single interface, eliminating the manual effort of cross-referencing multiple platforms and delivering an output that feeds directly into a sales follow-up workflow.

Four Questions to Verify a Real Equipment Manufacturer
- Do they have a machining workshop (turning, milling, grinding, drilling equipment) or a casting / welding production line — or do they rely entirely on outsourced assembly?
- For pressure-vessel or special-equipment products, can they provide a TS manufacturing license number (the number is publicly verifiable)?
- Do they hold their own process drawings and a customer supply list (which OEMs or engineering projects do they supply)?
- Do their job postings include specific process roles — rather than only "sales reps" or "purchasing specialists"?
Machinery Doors Are Hard to Open — but Once You're In, You Have a Long-Term Account
The machinery and equipment industry has one characteristic that many upstream suppliers underestimate: once a supply relationship is established, switching costs are extremely high. Casting drawings are developed by the factory itself — changing suppliers means re-sampling from scratch, followed by new dimensional verification and fatigue testing. Hydraulic components involve system-level matching; switching brands requires a full new test-bench validation, and the uncertainty involved means factories rarely disturb an existing supplier relationship.
This switching barrier cuts both ways. Getting in is difficult, but once you are in, you have stable repeat business for years. Precisely because of this dynamic, the accuracy of the first step — "knocking on the right door" — determines the return on investment across the entire sales cycle. Time spent on integrators and traders is not merely a waste of current call volume; it is also an open door for competitors to walk through first and occupy the purchasing window at a real factory.
What Tianxia Gongchang does in the machinery and equipment sector is to draw the line between "real factory" and "integrator / trader" at the list-building stage — before the first call is ever made. That means every effective visit an upstream supplier makes is directed at a factory that genuinely needs castings and hydraulic components, has a procurement budget, and is in active expansion mode. Cutting three-in-ten useless calls does not just save labor cost. It converts those three calls into three higher-quality customer relationships instead.
